Performance showdown: Windows 7 vs. Snow Leopard | |

Dong Ngo: As someone who uses both platforms for work and personal entertainment, I've been wanting to do a performance comparison between Windows 7 and Mac OS X since I first got my hands on the Windows 7 RTM (the final build of the OS) more than two months ago, but decided to wait until I could compare the two apples to apples. (No pun intended.) | ||

Interesting. The two applications that had built in benchmarking did better on Windows 7, while all other applications did better on OS/X using a stop watch... Not to mention he used Boot Camp for all the drivers in Windows 7 even though te OS's were installed on different hard drives, one a Hitachi and the other a Western Digital?
I guess the article did what it was suppose to. I clicked on it... |

| Snow Leopard is a lot slower on my Win7 PC........... |

This article is a PERFECT example of why you don't let laymen tech writers do serious benchmarking or technical reviews of OSes and hardware.
There are so many things that would affect the results it would take a longer article to explain how messed up this article is and how it is NOT reflective of anything. Here is one example to consider, the 'multi-tasking' benchmarks in this article shows OS X to beat Win7, yet as ANY OS ENGINEER will point out the OS X kernel is optimized for multi-tasking on one CPU core, and when it runs on multi-core computers, OS X has this horrible side effect called FUNNEL LOCKS, that essentiall shut down the additional core as applications and the OS isolated threads. This example BY DEFINITION means that OS X cannot multi-task as well as Win7 on a Dual-Core computer. This is why if you notice one of the applications the author used for rendering, was able to run faster on Win7, because the OS X CPU cores were possibly being locked. Additionally, the FUNNEL locks of the OS X kernel design means that if you only have ONE active application or two that probably don't force FUNNEL locking of the CPU cores, then multi-tasking will be somewhat OK, yet if you introduct JUST ONE application that creates FUNNEL locks in the OS, the whole system performance not only becomes bad at multi-tasking but can almost seem like a cooperative multi-tasking OS, as applications will start to 'stutter'. And 'stuttering' is not something you will EVER see in this context on a Windows NT OS because of the SMP handling in the kernel design. In fact, these 'locks' and 'stuttering' doesn't exist in Linux or OpenBSD either, as the FUNNEL locks of OS X are because of queue handling of single CPU multi-tasking that was attempted to be optimized with the MACH/BSD kernel mergers from the original XNU project. These 'locks' are also why the new multi-core libraries were added to Snow Leopard, but are a bandaid, as it doesn't fix the OS's ability to prevent funnel locks, it just provides an alternative development framework that avoids the funnel locks. i.e. Existing applications and any application not made with the new multi-core libraries will still bring OS X to locking the CPU cores, when Apple should have revisited the inherent flaw of the OS X kernel design that allows funnel locks. Next we could go on about Quicktime being used for benchmarks to the HORRID drivers supplied with Boot Camp that some believe Apple artificially retards or are just retarded about making them. Want a real test, go find ANY Vista or Win7 vs OS X test that runs mainstream applications available on both OSes, oh, for example, how about Adobe products - which virtually every test shows Vista and Win7 to be faster than OS X Tiger, Leopard, and Snow Leopard... Heck even go back to when Vista was 'doggy' before SP1 and optimized drivers: http://www.broadcastnewsroom.com/articles/viewarticle.jsp?id=167680 Give the 'real' tech world and OS Engineers a few more weeks to iron out Snow Leopard and Win7 and show the world that OS X is only faster when running Apple's own freaking Quicktime - Geesh... So, let's just leave it here that this article is sad, and painfully sad... This post was edited by thenetavenger on Friday, October 16, 2009 at 12:00. |

#3, Sad indeed and that is the perfect word for it.
Boot Camp? The basis for drivers? Are you kidding me? OK, perhaps "sad" isn't good enough here.... how about "criminal" "torturous" or "insane" "torturous interference?" Avenger is right, but does not carry it far enough - locking aside, the drivers used are not only NOT OPTIMIZED for Windows PC's, they may well be designed to provide a LESS THAN OPTIMAL experience as intended by Apple. Someone needs to take the author out back and just slap and I do mean slap, the ever loving fog out of his head. This kind of crap journalism should be exposed for the steaming pile of garbage it is. I am really sick of this sort of bunk. Snow Leopard is a mess and a serious problem for Apple and their users. It stinks and it sure as heck isn't even in the same universe as Windows 7 in any context. This post was edited by lketchum on Sunday, October 18, 2009 at 13:53. |

| Some people are a little butt hurt that Snow is faster than 7. :o) |
